AIR-MOISTENER.

secon, in the county of Atlantic and State of New Jersey, have inventedcertain new and useful Improvements 1n A1r-Mo1steners; and I do herebydeclare the followingto be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to This invention relates to air a part of the combustiblecharge; and it consists in the novel construction and combination of theparts" hereinafter fully described and claimed. i 1

In the drawings, Figure 1 is a side view of an air moistener constructedaccording to this invention. Fig; 2 is a vertical section through theair and Water valves, and is drawn to a larger scale.- Fig. 3 is a. planview of the same. Fig. 4 is a side view of the air moistener showingamodification.

A mixing chamber or pipe 2 is provided, for'air and for water in theform of fine spray, and is adapted to be connected to the intake pipe ofthe engine. ,This mixing chamber or pipe 2' is preferably passed througha heating-chamber 3 which is preferably the exhaust pipe or exhaustmanifold.

of the engine, so that the contents of the mixing chamber may be heatedby the waste products of combustion.

A valve casing 41: is provided, and is divided into two chambers by adiaphragm 5 of flexible material. The upper chamber 6, above thediaphragm, is an air chamber, and the lower chamber 7 is adapted to holdwater or other approved moistening fluid.

The lower chamber 7 has a water inlet pipe 8 connected to it, and 9 is avalve of any approved sort for drawing off the i vlae lower chamberhasan outlet 10 for water at its bottom, and 12 is a needle valve whichoperates as a spray-forming device, and which controls the passage ofwater through the outlet 10.

The stem 14 of the needle valve is secured in a metal disk 19 which -isattached to the center part of the'diaphragm. The upper end portion ofthe valve stem 14 works in a guide 15 secured to the top of the casing.

moisteners for use 1n connection with mt'ernal combus-- tlon engines tomolsten the a1r taken 1n as clearly seen. The connecting-piece has anThe guide isscrewed in the top of the easmg so that its position can beadjusted, and

16 is a jam nut for locking it in place. .A

-helical spring 17 is arranged in the guide around the valve stem, andis arranged be-- tween-the guide and the-disk 19 so that the needlevalve is pressed toward it seat and normally closes the outlet.Thetension of I g the spring 17 is varied by adjusting the positionofthe guide. A stop stem 20 is provided and is screwed into the top endofthe guide, and this stop stem projects downwardly so that theupper-end of the 'stem' of the needle valve 'may strike it. The stem 20is adjusted to ,vary the lift of the needle valve, or to holdit closed,if necessary. I A

helical spring 21 is arranged between the 1 accidental displacement topof the guide and the head 22 of the stop' piece 24; is arranged betweenthe lower part of-the casing 4 and the mixing chamber, and v is suitablysecured .tothe said parts. Two large inlet'openings 25 forv air areformed in the middle part of the connecting-piece 24, upon oppositesides of-it, and these openmg's form sight-holes through which the feedof water from the needle valve may be inlet valve 26 which opensdownwardly, or. inwardly toward the mixing chamberf This valve 26 isarranged below the level'of the holes 25, and it is normally seat by alight spring 27 A v The air space of the upper chamber 6' isconnected-with the mixing chamber andwith held to its the intake of theengine by means of a pipe 30. In the form of the device shown in Fig. 1,this pipe 30 is shown connected to the mixing chamber or pipe after ithas passed through the exhaust or heating pipe, and where the suction ofthe intake is con-1 siderable. in Fig. 4., the pipe 130 is connectedwith the.

In the form of the device shown mixing chamber or pipe before it entersthe pie is shorter, than in a causes the flexible diaphragm to moveupwardly and open the needle valve. The water rushes through the needlevalve and is projected in the form of spray through the inlet valve 26into the mixing chamber. The valve 26 is opened simultaneously with theopening of the needle valve, as the pressure in the mixing chamber isalso reduced below that of the atmosphere, and the air rushes formationof large drops of moisture .and.

vaporizes any drops which may be formed and which fallto the bottom ofthe mixing chamber. This enables the air to carry a I large supply ofmoisture with it into the engine cylinder.

This moisture prevents the formation of solid deposits of carbonin theengine cylin der, which would greatly interfere with the satisfactoryworking of the engine. When the engine is not at work, and when itscylinder is not drawing in a new charge, the

action of the moistener is suspended, as water valve is not opened.

What I claim is:

1. In an air moistener, a mixing chamber, an inlet valve for the saidchamber, a water valve, and an air-inlet piece' secured between the saidinlet valve and water valve, said valves both being operatedautomatically and independently of each other when the pressure in themixing chamber is reduced, and the said water valve operating to feedthe water through the airinlet piece and inlet valve into the mixingchamber.

2. In an air, moistener, a mixing chamber, an inlet valve for the saidchamber, a water valve, and' an air-inlet piece secured between the saidinlet valve and water valve and having air inlet openings at oppositesides of it which form sight-holes for the feed from the water valvethrough the said inlet valve into the L mixing chamber, said valvesbeing operated automatically and independently of each other when thepressure in the mixing chamber is reduced.

3. In an air moistener, a mixing chamber, an inlet valve for the mixingchamber, a casing, a diaphragm secured in the casing and separating itinto a water chamber and an air chamber, a water valve controlled by thesaid diaphragm and operatively connected with the said mixing chamber,and a pipe connection between the said air chamber and the mixingchamber, whereby the said inlet valve and water valve are openedsimultaneously when the pressure in the mixing chamber is reduced belowthat of the atmosphere.

4:. In an air moistener, a mixing chamber, an inlet valve for the saidchamber, a water valve, and an air-inlet piece secured between the saidinlet valve and. water valve and provided with a sight-hole for the feedfrom the water valve, said inlet valve and water valve beingoperatedautomatically when the pressure in the mixing chamber is reducedbelow that of the atmosphere.

5. In an air moistener, a mixing chamber, an inlet valve for the mixingchamber, a casing, a flexible diaphragm secured in the casing andseparating it into a water chamber and an air chamber, a water valvecontrolled by the said diaphragm and discharging into the mixingchamber, a spring normally closing the said water valve, a stop forregulating the lift of the said water valve, and a pipe connectionbetween the air chamber and the mixing chamber.

6. In an airmoistener, a mixing chamber, an inlet valve for the mixingchamber, a casing, a diaphragm secured in the casing and separating itinto a water chamber and an air chamber, a water valve controlled by thesaid diaphragm and operatively connected with the said mixing chamber,and a pipe connection secured to the said air chamber and operativelyconnected with the delivery end portion of the said mixing chamber.

In testimony whereof I have aflixed my signature.
